IDT2309NZ
NINE OUTPUT
3.3V CLOCK BUFFER
FEATURES:
DESCRIPTION:
• One input to nine output buffer/driver
• Supports two DIMMs or four SO-DIMMs with one additional
output for feedback to an external or chipset PLL
• Low power consumption for mobile applications: less than
32mA at 66.6MHz with unloaded outputs
• 8.7ns input-output delay
TheIDT2309NZisalow-costbufferdesignedtodistributehigh-speed
clocks in mobile PC systems and desktop PC systems with SDRAM
support. This part has nine outputs, eight of which can be used to drive
twoDIMMsorfourSO-DIMMs,andtheremainingcanbeusedforexternal
feedbacktoaPLL. TheIDT2309NZoperatesat3.3Vandoutputscanrun
up to 133.33MHz
• Buffers all frequencies from DC to 133.33MHz
• Output-output skew < 250ps
• Multiple VDD and VSS pins for noise and EMI reduction
• 3.3V operation
TheIDT2309NZisdesignedforlowEMIandpoweroptimization. Ithas
multiple VDD and VSS pins for noise optimization and consumes less than
32mAat66.6MHz,makingitidealforthelowpowerrequirementsofmobile
systems.
• High drive capability
• Available in SOIC and TSSOP packages
